For the , it is a torch in the dark—showing that the first step is not to solve IMO Problem 6, but to master the art of the well-chosen example. For the intermediate competitor , it is a gym—full of targeted drills, from "warm-up" inequalities to "marathon" combinatorial designs. For the advanced student , it is a reference and a source of subtle counterexamples that sharpen intuition. a mathematical olympiad companion

Olympiad problems are often designed to look novel and unfamiliar. A companion focuses on teaching the art of isomorphism —showing how a seemingly impossible geometry problem is actually just a variation of a classic algebraic inequality, or how a number theory puzzle is a disguised version of the Pigeonhole Principle. It teaches students to strip away the "costume" of the problem to reveal the familiar math underneath. Ultimately, a Mathematical Olympiad Companion is a promise:
